  • Control Of Exposure In Printing And Copying (AREA)

Abstract

PURPOSE: To finish photographs to good color balances by measuring the large area mean transmission density of multiple color photographic films of a predetermined range, calculating the mean value thereof, and using this mean value as a standard value.
CONSTITUTION: If it is assumed that the mean value of a certain month is B where a reference value is defined as A, exposure is made by changing the reference value to B. Namely, a deviation amount between the reference value A and the mean value B is obtained and exposure conditions are corrected by this deviation amount. Besides such seasonal variations, there are variances in developing conditions and variances in characteristic curves; therefore, the mean values of, for example, 1,000W10,000 frames are calculated at every certain period, and with these as a mean value, the exposure conditions are changed.
